Substitutes a formula string by given rules.
Formula that this node uses to substitute variables.
Rules for substituting variables.
Name of the parameter that this node looks for in formula.
parameter name can contain any number of valid characters. If parts of the original string represent numbers like 1E-2, the parameter name cannot begin with capital letter E. Otherwise, this node produces unpredictable errors.
Content of the parameter. parameter content must have a one-to-one relation with parameter name.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Final formula after all substitution rules are performed.
Error information.
The node produces this output according to standard error behavior.

The following table shows an example of the inputs and outputs of this node.
formula | substitution rules | formula after substitution | |
---|---|---|---|
ALPHA * cos(t) + beta | parameter name | parameter content | (sin(t))*cos(t)+(2*t*exp(t)) |
ALPHA | sin(t) | ||
beta | 2 * t * exp(t) |
